The behaviour and detection of radioactive aerosols in Natacha
Radioactive aerosols differ from their non-radioactive counterparts in being able to charge themselves by the emission of charged decay products. For beta-decaying aerosols their net charge is then a balance between the positive self-charging and neutralization by negative ions produced in the surrounding gas. The current PHEBUS fission product project affords a unique opportunity to investigate the charging and behaviour of actual fission product aerosols formed by overheating reactor fuel in severe accident conditions. This paper describes an apparatus, NATACHA, designed to detect charged particles in PHEBUS by subjecting them to an electric field.
